HYD RANT. i

SPECIFICATION forming part of Letters Patent No. 269,440, dated December1 9, 1882. Application filed June 24, ISSQ. (No model.)

To all whom it may concern: Be it known that I, WILLIAu MCNAMAEA, ofCleveland, in the county of Uuyahoga and State ot' Ohio, have inventednew and useful Improvements in Hydrants, of which the following is,adescription of the construction and operation thereof, reference beinghad to the annexed drawings, making` a part of this specitication, inwhich- Figure l shows an external side view otthe machine. Fig. 2 is atransverse longitudinal ysection. Figs. 3, 4, and 5 are detachedsections.

Like letters ot' reference denote like partsin the several views. rIhelower part or s cction ofthe `hydrant consists of a tubular shell, A,having on each ot' two opposite sides a conduit, B and C, respectively,which are in open communication with the shell at a and b, Fig. 2. Insaid shell is tted, in a water-tight manner, a tubular core, D, adetached longitudinal section .ot' which is shown in Fig. Said `core ismade water-tight in the shell by means of packing c; Between saidpacking the surface otl the core is cut away, forming'an annular recess,e, Fig. 3. atf. Said recesses, when the coreisin theshell, form, withthe sides thereof, annular chambers a and Z1', the purpose ot which willpresently be shown. "itliin the core is movably fitted a hollowvalve-stem, E, made water-tight therein by means of packing c'. To thelower end of the stem is secured a valve, F, having its seat inthe lowerend ofthe shell A, t'or opening and closing the water-passage G. To thesaid valve-stem is secured a rod, H, passing through the tube ordry-pipe l, the lower end ot' which pipe is screwed into the'core, asseen at J, Fig. 2. To the above-described lower section of the hydrantis screwed a pipe, K, inclosing the tube l. The opposite end ot' thepipe is secured to the upper end ct' the hydrant, consisting ot' ashell, A', provided with a discharging-nozzle, B. In said shell A/is acylinder, C', to the bottom of which is screwed the upper end of thetube I, thereby connecting the core D ot' the lower section of thehydrant with the cylinder C', as seen in the drawings. In said cylinderis fitted, so as to slide therein, a block,D/. 0n two sides ofthe blockare ribs m, adapted respectively to fit and Slide in the slots n, madein the sides of the A similar recess is made in the core therein. Theblock is operated by a screw, E',

attached thereto by a flanged head, N, loosely iitted in the block, andwhich is prevented from being-pulled out therefrom by the flange of thehead, adapted to engage a correspond-4 ing annular shoulder formed inthe block,

thereby making a swivel-connection ot' the screw and head, substantiallyas lseen in Fig. 2. The screw is retained in the block by a nut, i,screwed therein, and to which nut the valve-rod H is attached, therebyconnecting the screw E', by means of the rod, to the valve F foroperating it. rIhe thread ot' the screw E isa coarseone and works in anut, F', screwed into the shell A', as seen in Fig. 2.

The core D, above alluded to, is made up in sections 1, 2, 3, and 4,-asseen in Fig. 3, for the convenience of providing the core with 'packing.It will be observed that the several sections are connected to eachother by screwjoints, and that between the collars ot' the sections thepacking is secured.

I do not contne myself to the construction of the core as abovedescribed, as it may be otherwise made or modified without departingfrom its general structure.

The practical operation ofthe hydrant is as follows: The lower sectionof the machine is set down in the ground as low as the watermain', andis attached thereto by the pipe O in the usual way. As in ordinaryhydrants, the `upper section is near the surt'ace ot' the ground. Tothis end the pipe K, &c., may be longer or shorter, as the setting ofthe hydrant may require. As shown in the drawings, the valve F isscrewed down upon its seat, thereby shutting olf the water from thehydrant. Now, on turning the screw E in the proper direction the block Dis drawn upward in the cylinder C', and with it the connecting-rod H,which, as a consequence, will lift the valve F from itsseat and allowthe water to liow from the pipe 0 into the conduits B C, which passesupward therein and outl ofthe openings b b into the pipe K, up whichit'passes to the discharging-nozzle B.

The passage of the water is in- I licated by the arrows. On turning downthe screw E' the valve closes, shutting off the water from the hydrant.That which may be left in the pipe K and the conduits flows therefromthrough the waste-hole u' into the hollow stem E of the valve, up whichit passes to the venthole t', and is discharged therefrom into theannular chamber a', from thence to the outside of the hydrant, throughthe hole i', Fig. 1, in the side of the shell, thus leaving lthe hydrantfree of water.

It will be obviousfrom the above that water cannot lodge in the pipe Kwhen shut oi' from entering the hydrant; nor can it find its way intothe dry-pipe I to the valve-rod H, the water being excluded therefrom bythe close water-tight joints and packing. Hence the rod H is always keptdry, so that it will work easily, and not be liable to freeze up; norcan the water find its way above the discharging-nozzle,

as the packing r at the lower end of the cylinder closes the passage-Wayabout the pipe I, screwed in to the cylinder, said cylinder beingscrewed down upon its bearings in section A' by the screw-nut F', makingthe whole connection Water-tight.

In operating the hydrant the core remains stationary, the valve onlybeingthe part moved for opening and closing the hydrant. Hence there isbut little frictional wearing ot' the parts in Working the hydrant,which may be used either with or without a stock. Should water leak fromthe pipe K around the upper' end of' the core, it can go no farther thanto the annular chamber b', Fig. 2, and will run therefrom to the outsidethrough the wasteholef' in the side of the core and a corresponding holein the side of the shell, as seen atf' in Fig. 1.

In the drawings the waste-holes are shown as being both on the same sideof the shell.

It is preferred to have one on each side, instead of both on one side.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In hydrants,in combination with the shell A and side conduits in opencommunication with said shell, the tubular core provided with exteriorrings of packing and exterior annular recesses, forming, with the sidesof the shell, annular chambers having waste-openin gs, substantially asdescribed, and for the purpose set forth.

2. In hydrants, the core D, providedv with internal packing-rings, c,and annular recesses, in combination with the tubular valve-stem andvalve, and shell A', having an outlet, B', substantially as described,and for the purposes set forth.

3. In combination with the tubular core, valve-stem E, and shell, thevalve-rod H, pipe I, inclosing said rod, water-pipe K, connecting theshell A and shell A', in the manner substantially as and for the purposespecified.

4. In combination with the pipe I and valverod, the slotted cylinder,screw-stem E', loosely connected to the block D', shell A', and screwnut, substantially as described, and for the pury pose set forth.

5. The core D, consisting of sections connected to each other byscrew-joints, and having interior and exterior packing and interior andexterior recesses, provided with wasteholes, in combination with theshell A and valve-stem, as and for the purpose specified.

In testimony whereofI ax my signature in presence of two witnesses.
